..DISCUSSION
MID-LEVEL NORTHWESTERLY FLOW IS FORECAST TO BECOME ESTABLISHED
ACROSS THE CENTRAL U.S. ON MONDAY. THIS APPEARS LIKELY TO PERSIST
INTO MID-WEEK AS A LARGE-SCALE TROUGH DEVELOPS IN THE MISSISSIPPI
VALLEY. THE PATTERN WILL HELP TO USHER COLD AND DRY AIR SOUTHWARD
INTO THE GREAT PLAINS AND SOUTHEAST, WHICH WILL LIMIT MOISTURE
RETURN. FROM THURSDAY INTO FRIDAY, THE TROUGH IS FORECAST TO MOVE
INTO THE EASTERN U.S., REINFORCING NORTHWESTERLY MID-LEVEL FLOW OVER
MUCH OF THE NATION. AS A RESULT, A COLD AND DRY AIRMASS IS EXPECTED
TO REMAIN OVER THE CONTINENTAL U.S, MINIMIZING THE POTENTIAL FOR
THUNDERSTORM DEVELOPMENT.
